Humpback Grouper
Chromileptes altivelis
Humpback Grouper (Chromileptes altivelis) is a reef-associated serranid with a very tall, arched back and striking black-and-white spotting. It is a slow-growing coral-reef predator that hides in holes and ledges and is valued more in aquaria than as a target species.
Identification points
- Deep, hump-backed body with an unusually tall arched dorsal profile
- White body covered in dense black spots
- Broad dark saddle-like bars on the head and body, with a small mouth typical of grouper
Habitat
Coral reefs, lagoon drop-offs, outer reef slopes, and rubble fields with caves, crevices, and overhangs; usually near structure from shallow water to moderate depths.
Bait notes
Small live reef fish, shrimp, squid strips, and cut bait are most effective; small jigs or soft plastics worked tight to structure can also draw strikes.
Behavior
A sedentary ambush predator that waits in cover and darts out to take small fish and crustaceans; often solitary and more active around dusk and at night.
Caution
Avoid consumption from areas with ciguatera risk; large reef grouper can carry toxin. Check local size/collection rules, as this species is often protected or restricted in parts of its range.
Fishing notes
Fish slowly and precisely around holes, bommies, and ledges with enough tackle to stop a dive into cover; keep presentations close to the bottom and pause often.
